Qi Min asked Zhang Zhiyong on WeChat if there were any fluorescent dyes with better stability.

Zhang Zhiyong replied after a while: "You don't need quantum dots." ”

"What are quantum dots?" Qi Min asked.

ZHANG ZHIYONG DID NOT REPLY IMMEDIATELY, BUT DUMPED HER FOR A REVIEW.

Really...... Hardcore. Qi Min couldn't help but scold, does ordinary PI really have no human rights? If the leader of the biology department asked him about fluorescent dyes, he probably wouldn't dare to dump the literature so directly.

QI MIN SLUMPED ON THE SOFA AND READ THE REVIEW, AND FROM THE SUMMARY AND SUMMARY, HE ROUGHLY UNDERSTOOD WHAT QUANTUM DOTS ARE AND WHAT THEY CAN DO. The so-called quantum dots are tiny semiconductor particles at the nanoscale, which have been fully studied in nanotechnology, and are called "quantum dots" because of the ability of electrons to quantum-realize the transition from valence to conduction bands. Quantum dots can be used as an alternative to common organic fluorescent dyes in biological applications and can be approximated as point dipoles in the model, allowing them to be used in FRET technology.

This is very good news for Qi Min. She used FRET to detect neuronal activity, and now if she can continue to use FRET, it will be very beneficial to coherent logic in the article.

However, if you are conducting in vivo experiments, you can't use quantum dots made of metallic materials – they are usually biotoxic. AND WHEN IT COMES TO NON-METALLIC QUANTUM DOTS, QI MIN ONLY SAW PEPTIDE QUANTUM DOTS IN THIS REVIEW, AND THIS EARLY ARTICLE SHOWS THAT PEPTIDE QUANTUM DOTS WERE STILL IN THE RESEARCH STAGE AT THAT TIME.

Qi Min asked Zhang Zhiyong on WeChat: "If it is used on living brain tissue, do you think peptide quantum dots are appropriate?" ”

"It should be fine. I have it in my lab, do you? Zhang Zhiyong replied.

Qi Min hesitated. She had never operated quantum dots before, so the people in her lab had to learn from the people in Zhang Zhiyong's lab. But if you let Ke Li learn, it will inevitably seem a bit overstepping, after all, Ke Li is a doctoral student of researcher Zhou Xiaoshan. But if Wang Xin and Chen Linyou are to go, the two first-graders may not have anything wrong.

At this time, Zhang Zhiyong probably saw that she was slow to reply, and sent another message: "Mutual assistance from the same school is provided free of charge, rest assured that I will not rub your common communication." ”

Seeing him like this, Qi Min couldn't help but want to laugh. In her eyes, Zhang Zhiyong is a great god, and the great gods disdain to rub other people's articles. What's more, Qi Min has already cooperated with researcher Zhou Xiaoshan on this topic, and if the corresponding author wants to hang the name of his predecessor, I am afraid that he will not be able to hang Zhang Zhiyong anymore.

However, objectively speaking, if he just provides a peptide quantum dot, he really can't talk about being named.

"When am I going to pick it up?" Qi Min asked in WeChat.

Zhang Zhiyong replied: "Even if you come to get it yourself, you won't get it." SEND ME A COPY OF YOUR EXPERIMENT PROTOCOL FIRST. ”

QI MIN SENT A COPY OF THE PROTOCOL FOR KE'S BRAIN-COMPUTER CONNECTION EXPERIMENT TO ZHANG ZHIYONG. She didn't worry about leaks, Zhang Zhiyong was in a chemistry laboratory, and she couldn't do this anymore.

Zhang Zhiyong didn't reply for twenty minutes, and then replied: "Okay, I'll prepare the sample on Tuesday, and I have to go over and teach you." ”

——

Zhang Zhiyong said that giving her the sample on Tuesday made Qi Min subconsciously have the idea that she could skip work on Monday. And since she didn't have to go to the lab on Monday, she didn't want to think about any experiments on Sunday night.

Qi Min habitually picked up the set-top box remote control, and just called up the movie collection, but heard Anton shouting outside: "Come out to eat!" ”

Hearing the summons, Qi Min could only go out, and couldn't help but sigh in his heart, in the past, Anton asked her to eat when he walked to her side, and at least he would bring a title. Now he shouted from afar without a name, but Qi Min had to go over automatically, it was really ...... She brought it on herself.

But the rice is delicious. Today's main dish is braised beef, vegetarian dishes are braised eggplant with mushrooms and garlic oil and wheat vegetables, and the snack is boiled shrimp with rock sugar pear water boiled in a new casserole.

Mimi was scooping the pear water in the bowl with a small spoon, and Anton saw it and hurriedly stopped: "Don't, Mimi, let it cool and drink it again......"

He saw Qi Min coming out of the bedroom and said directly to her, "Go and serve the meal yourself." ”

In fact, he has cooked all the meals, and it is also convenient to give Qi Min a bowl by the way. However, Anton wanted to express his dissatisfaction with her in this way, and Qi Min could only admit it.

She sat down at the table with her meal, habitually picking up the remote control and turning on the TV.

Don't look at the small house she rented, there are even two TVs. A normal-sized TV with a set-top box is in the master bedroom, while the dining room with an attached kitchen has a small TV that doesn't have a set-top box or internet access. Even so, small TVs can still be watched.

Qi Min likes to eat with nature documentaries, but when he turns on the TV, it happens to be on the animation channel. She saw that Mimi was obviously interested in this, so she had to give up the idea of changing the channel.

Suddenly Qi Min felt that it was also a good way to let Mimi watch Chinese TV, and she watched Chinese cartoons, naturally to adapt to the Chinese context. After all, children can't stop watching TV.

And since there was no proper TV show to watch, Qi Min had to focus on eating - and this dinner was really good. After rescuing her numb taste buds with spinach and pork liver porridge at noon, Qi Min also felt that her sense of taste had become much clearer when she tasted this dinner.

However, just as she stretched out her chopsticks to cook shrimp, Anton suddenly slapped her hand with chopsticks: "You can eat less." ”

"What's wrong?" Qi Min was inexplicable.

"How many pieces have you eaten? There weren't a few pieces in total. Anton said, "Leave Mimi some." ”

Qi Min glanced at it, and there were still a lot of shrimp on the plate. She had the impression that Mimi couldn't eat much at all, and she ate very slowly, so she had always eaten as much as she wanted.

More than half a year has passed, and Mimi may have eaten more, but it is unlikely that she will be able to eat a whole plate of cooked shrimp at once. The only possibility is that Anton deliberately scolded her.

Yes...... Let's just scare. Qi Min took back his chopsticks, took two sticks of oily wheat cabbage and took them back to chew.

Anton saw that she could only chew greens, and was finally satisfied. However, when she turned around, she saw Mimi secretly spooning back the oily wheat vegetables in her bowl, and immediately pulled down her face to criticize her: "Mimi, eat so good!" ”

Mimi immediately pulled the vegetable chop back into her bowl.

However, within half a minute, the little girl asked Qi Min again, "Mom, do you want to eat vegetables?" ”

Before Qi Min could answer, Mimi pushed her small bowl to Qi Min's bowl and pulled the oily wheat vegetables into her bowl with a spoon.

Qi Min couldn't cry or laugh, so he had to refuse: "Mom doesn't want to eat vegetables." ”

Hearing her say this, Mimi immediately said to Anton: "Mom doesn't want to eat vegetables either." Why do I have to eat? ”
